For example, during heating a portion of the permeable body is removed as hydrocarbons are liberated. The remaining materials (e.g. silica and other minerals) of the hydrocarbonaceous portion of the permeable body can at least partially collapse.

  • Permeable bodies suitable for use in the present invention can have greater than about 10% void space and typically have void space from about 20% to 50%, although other ranges may be suitable. Allowing for high permeability facilitates heating of the body through convection as the primary heat transfer mechanism while also substantially reducing costs associated with crushing to very small sizes, e.g. below about 2.5 to about 1 cm. Specific target void space can vary depending on the particular hydrocarbonaceous material and desired process times or conditions.
  • mined refers to a material which has been removed or disturbed from an original stratographic or geological location to a second and different location.

  • any circulation and/or flow of hydrocarbonaceous material such as that found in fluidized beds or rotating retorts involves highly substantial movement and handling of hydrocarbonaceous material.
  • adjacent refers to the proximity of two structures or elements. Particularly, elements that are identified as being “adjacent” may be either abutting or connected.

  • the present method can provide an effective means for recovering hydrocarbons from organic rich hydrocarbonaceous materials without substantial subsidence within the constructed permeability control infrastructure.
  • the use of structural materials within the permeable body can maintain a desired porosity such that convective flow of fluids is maintained during processing.
  • Such a method can be particularly effective for comminuted hydrocarbonaceous materials that generally do not maintain porosity under typical processing conditions.
  • the constructed infrastructure can define a substantially encapsulated volume where a composite comminuted hydrocarbonaceous material, including a mined or harvested hydrocarbonaceous material and a structural material, can be introduced into the control infrastructure to form a permeable body of composite material.

In this manner, a grid of constructed structures can be built such that mined material can be immediately and directly filled into an adjacent impoundment.
  • the impoundment can be formed of a suitable material which provides isolation of material transfer across walls of the impoundment. In this manner, integrity of the walls is retained during operation of the control infrastructure sufficient to substantially prevent uncontrolled migration of fluids outside of the control infrastructure.

  • Impoundment floor and wall construction can, but need not comprise, a stepped up or stepped down slope or bench as the case of mining course may dictate following the optimal ore grade mining.
  • floor leveling and containment wall construction can typically drain or slope to one side or to a specific central gathering area(s) for removal of fluids by gravity drainage assistance.
  • capsule wall and floor construction can include insulation which prevents heat transfer outside of the constructed infrastructure or outside of inner capsules or conduits within the primary constructed capsule containment.

  • the composite comminuted hydrocarbonaceous material can provide 50% to 60% porosity.
  • the permeable body can have a first porosity before heating and a second lower porosity during and after heating which is maintained above 10%.
  • hydrocarbon containing material can be classified into various inner capsules or cells within a primary constructed infrastructure for optimization reasons. For instance, layers and depths of mined oil shale formations may be richer in certain depth pay zones as mining progresses. Once blasted, mined, shoveled and hauled inside of a capsule for placement, richer oil bearing ores can be classified or mixed by grade for optimal yields, faster recovery, or for optimal averaging within each impoundment. The ability to selectively control the characteristics and composition of the permeable body adds a significant amount of freedom in optimizing oil yields and quality. Furthermore, the liberated gaseous and liquid products can act as an in situ produced solvent which supplements kerogen removal and/or additional hydrocarbon removal from the hydrocarbonaceous material.
  • the permeable body can further comprise an additive or biomass.
  • Additives can include compositions which act to increase the quality of removed hydrocarbons, e.g. increased API, decreased viscosity, improved flow properties, reduced wetting of residual shale, reduction of sulfur, hydrogenation agents, etc.

  • manmade materials can also be used as additives such as, but not limited to, tires, polymeric refuse, or other hydrocarbon-containing materials.
  • the permeable body can include comminuted hydrocarbonaceous particles from about 0.3 cm to about 2 meters on average, and in some cases less than 30 cm and in other cases less than about 16 cm on average. However, as a practical matter, sizes from about 5 cm to about 60 cm on average, or in one aspect about 16 cm to about 60 cm on average, can provide good results with about 30 cm average diameter being useful for oil shale especially. Additionally, the permeable body can include structural materials having an average size from about 16 cm to about 1.5 meters. In one aspect, the structural materials can have an average size from about 30 cm to about 1 meter.
  • the permeable body can comprise a bimodal size distribution of comminuted hydrocarbonaceous material and structural material.
  • Structural materials can be particulate and often have an average size from about 0.3 cm to about 2 meters. Although the average size can be commensurate with particle size ranges of the hydrocarbonaceous material, in some cases, the structural material can have an average diameter which is larger than an average diameter of the hydrocarbonaceous material. Accordingly, it can be desirable to provide structural material having an average size which is from about 10% to about 500% larger than an average size of the hydrocarbonaceous material.
  • the bimodal size distribution can include a majority of structural material having an average diameter that is at least twice an average diameter of the comminuted hydrocarbonaceous material.
  • the bimodal size distribution can provide a porosity of between 10% and 80% for the permeable body before and during heating. In one specific aspect, the bimodal size distribution can provide a porosity of between 40% and 70% for the permeable body before and during heating.
  • Void space can be a factor in determining optimal particle diameters. However, about 15% to about 40% and in some cases about 30% usually provides suitable results. Void volumes can be varied somewhat by varying other parameters such as heating conduit placement, particle size distributions (i.e. multimodal distributions), additives, and the like. Mechanical separation of mined hydrocarbonaceous materials can allow for creation of fine mesh, high permeability particles which enhance thermal dispersion rates once placed in capsules within the impoundment, which can be further enhanced by the present structural materials.
  • the added permeability allows for more reasonable, low temperatures which also help to avoid higher temperatures which result in greater CO 2 production from carbonate decomposition and associated release of trace heavy metals, volatile organics, and other compounds which can create toxic effluent and/or undesirable materials which can be monitored and controlled.
  • the composite comminuted hydro carbonaceous material can be filled into the control infrastructure to form the permeable body in a suitable manner.
  • the comminuted hydro carbonaceous material can be conveyed into the control infrastructure by dumping, conveyors or other suitable approaches.
  • the permeable body can have a carefully tailored high void volume. Indiscriminate dumping can result in excessive compaction and reduction of void volumes.
  • the permeable body can be formed by low compaction conveying of the composite hydrocarbonaceous material into the infrastructure. For example, retracting conveyors can be used to deliver the material near a top surface of the permeable body as it is formed.
  • zones of hydrocarbonaceous material can be formed having varied void volumes.
  • Impoundment walls 20 isolate the permeable body 22 from surrounding formation 24.
  • Lower void volumes can result in lower convective heat currents. Consequently, convective heat flows can be controlled by providing variations in void volumes across the permeable body.
  • layers of hydrocarbonaceous material can have alternating higher and lower void volumes (i.e. high void volume layers 26 , 28 and 30 , with low void volume layers 32 , 34 and 36 ).
  • convective heat flow can flow more freely along zones having higher void volume over zones having relatively lower void volume.
  • Low void volume layers can thus act as convective flow retarding layers.
  • void volume can be varied horizontally in order to develop convective flows which distribute heat in a desired pattern.
  • low void volume zones 38 , 40 and 42 can be distributed to interrupt and/or redirect convective heat flow. Heat distribution uniformity can be increased, localized hot spots can be reduced, and/or convective flow rates can be reduced.
  • heat can be introduced sufficient to begin removal of hydrocarbons, e.g. via pyrolysis.
  • a suitable heat source can be thermally associated with the permeable body.
  • Optimal operating temperatures within the permeable body can vary depending on the composition and desired products. However, as a general guideline, operating temperatures can range from about 93 °C to about 430 °C. Temperature variations throughout the encapsulated volume can vary and may reach as high as 900 °F or more in some areas. In one embodiment, the operating temperature can be a relatively lower temperature to facilitate production of liquid product such as from about 93 °C to about 340 °C. This heating step can be a roasting operation which results in beneficiation of the crushed ore of the permeable body. Generally, products can include both liquid and gaseous products, while liquid products can require fewer processing steps such as scrubbers etc.
  • Heat can be transferred into and throughout the permeable body primarily via convection.
  • Heated gases can be injected into the control infrastructure such that the heated gases pass throughout the permeable body.
  • Heated gases can be produced by combustion of natural gas, hydrocarbon product, or other suitable source.
  • the heated gases can be imported from external sources or recovered from the process of the present invention.
  • the heated gases can be directed through the permeable body via embedded heating conduits. In this manner, the heating gases can be provided in a closed system to prevent mixing the heated gases with the permeable body.
  • the plurality of conduits can be readily oriented in a variety of configurations, whether substantially horizontal, vertical, slanted, branched, or the like. At least a portion of the conduits can be oriented along predetermined pathways prior to embedding the conduits within the permeable body. The predetermined pathways can be designed to improve heat transfer, gas-liquid-solid contacting, maximize fluid delivery or removal from specific regions within the encapsulated volume, or the like. Further, at least a portion of the conduits can be dedicated to heating of the permeable body. These heating conduits can be selectively perforated to allow heated gases or other fluids to convectively heat and mix throughout the permeable body.
  • the heating conduits can form a closed loop such that heating gases or fluids are segregated from the permeable body.
  • a "closed loop” does not necessarily require recirculation, rather isolation of heating fluid from the permeable body.
  • heating can be accomplished primarily or substantially only through thermal conduction across the conduit walls from the heating fluids into the permeable body. Heat transfer within the permeable body then proceeds primarily via convective heating.
  • the heating conduits can allow for substantial elimination of such localized hot spots while maintaining a vast majority of the permeable body within a desired temperature range.
  • the degree of uniformity in temperature can be a balance of cost (e.g. for additional heating conduits) versus yields.

  • the systems can allow for recovery of hydrocarbons while eliminating or substantially avoiding production of undesirable leachates.
  • crushed oil shale material can directly produce a liquid product having an API from about 30 to about 45, with about 33 to about 38 being currently typical.
  • pressure appears to be a much less influential factor on the quality of recovered hydrocarbons than temperature and heating times.
  • heating times can vary considerably, depending on void space, permeable body composition, quality, etc., as a general guideline times can range from an hour up to about one year. In one specific example, heating times can range from about 2 weeks to about 4 months. Under-heating oil shale at short residence times, i.e.

  • the walls can be constructed having a substantially uniform thickness which is optimized to provide sufficient mechanical strength while also minimizing the volume of wall material through which the conduits pass. Specifically, excessively thick walls can reduce the amount of heat which is transferred into the permeable body by absorbing the same through conduction. Conversely, the walls can also act as a thermal barrier to somewhat insulate the permeable body and retain heat therein during operation.
  • the present constructed permeability control infrastructure can be heated and/or cooled under specific temperature profiles to substantially eliminate or minimize the formation of unwanted accumulated hydrocarbon material.
  • the present infrastructures can be operated to heat at least a portion of the permeable body to a bulk temperature above a production temperature sufficient to remove hydrocarbons therefrom, where conditions in non-production zones are maintained below the production temperature.

  • the fluid barrier properties of the impoundment barrier layer can be maintained. For example, when using bentonite amended soil (BAS) the fluid barrier properties are maintained as long as the BAS layer is hydrated.
  • hydration can be maintained by keeping temperatures throughout the BAS layer below about 100 °C, or more typically below about 93 °C in order to avoid hot spots and localized dehydration of the BAS.

  • Exterior capsule impoundment side walls 102 provide containment and can, but need not be, subdivided by interior walls. Subdividing can create separate containment capsules or cells within a greater capsule containment of the impoundment 100 which can be any geometry, size or subdivision. Further subdivisions can be horizontally or vertically stacked. By creating separate containment capsules or chambers, classification of lower grade materials, varied gases, varied liquids, varied process stages, or other desired and staged processes can be readily accommodated. Such sectioned capsules can provide additional environmental monitoring and can be built of lined and engineered tailings berms similar to the primary exterior walls. Lower content hydrocarbon bearing material can be useful as a combustion material, as fill, or as a berm wall building material.

Of particular interest is hydrocarbon combustion performed under stoichiometric conditions of fuel to oxygen. Stoichiometric conditions can allow for significantly increased heat gas temperatures. The combustion off gases can then be sequestered without the need for further separation, i.e. because the off gas is predominantly carbon dioxide and water.
  • in-capsule combustion can be initiated inside of isolated capsules within a primary constructed capsule containment structure. This process partially combusts hydrocarbonaceous material to provide heat and intrinsic pyrolysis. Unwanted air emissions can be captured and sequestered in a formation 108 once derived from capsule containment or from heat source 134 and delivered by a drilled well bore.
